get the FX-8320 instead of the FX-8150
10-15% better singlethreaded performance
also the 8320 runs cooler so you can get the 212+ cpu cooler instead, which costs less
hyper evo 212 cooler

i'm just making suggestions of course, but really try and put more for a case!!
Spenlard recommendations are good.
my 2 cents: hate the case but it's all down to personal preferences ( theres much better cases in the 110$ price range)
